What do a scraped knee, a paper cut, or any form of surgery have in common? The short answer is a wound in need of healing—but the long answer lies in a series of biological activities that allow tissues to repair themselves.
Scientists have deciphered a key strategy of cancer cells that allows them to outfox the immune system and enhance the odds of their survival by employing a deadly "two-faced protein" that is reminiscent of a two-faced figure ...
No matter the pathogen—virus, bacterium or fungus—many "pick a specific type of lock" on the surface of cells, which allows the microbe to break and enter into the inner sanctum of the host's genome.
Losing the activity of a key ion channel in the brain may contribute to the buildup of a devastating and toxic protein responsible for the clumps of plaque that accumulate in Alzheimer's disease, a team of neurobiologists ...
Questions abound when it comes to the molecular mechanisms deployed by the human immune system to thwart cancer and infection, and questions especially abound when it comes to the precise steps taken by the innate immune ...
The entire family of coronaviruses is equipped with multiple methods of evading the human immune system, and two new studies have taken a deep dive into how these viruses, including SARS-CoV-2, leverage highly specialized ...
An experimental drug that is already in clinical trials for other diseases could disrupt a positive feedback loop that exacerbates pulmonary arterial hypertension, a dangerous and rapidly fatal condition for which there is ...
Premature rupture of the amniotic sac can have devastating consequences, but scientists in Japan are studying instances when the damaged sac repairs itself—a phenomenon that requires cooperation of the developing fetus.
The immune system is an extraordinarily complex network made up of components that simultaneously launch attacks and mount defenses.
The molecular world is full of surprises, and none more stunning than those occurring among the infinitesimal proteins that drive the activities guarding against viral infections and cancer.
